VACUUM CLEANING APPARATUS Filed Feb. 8, 1930 Carl lt@ M; f 1M Patented Mar. 14, 1933 Pa'rEN'lfI OFFICE CARL OTTO,'OF ESSEN'QBREDENEY, GERMANY VAUUM CLEANING APPARATUS Application tiled February 8, 1930, Serial No.

My invention relates to improvements in vacuum cleaning apparatus, and more par-A ticularly to apparatus of the type in which beaters are associated with thev nozzle for more effectively cleaning the vcarpet or the like.- The object of the improvements is to provide an apparatus which is eiiective in operation and with this object in view my invention consists in constructing the operating mechanism of the beater in the form of a magnetic hammer break. Preferably the lbeater is constructed so that it has' a rubbing or .sweeping action in addition to beating action. Finally an object of the improvements is to construct the beating apparatus so that it can be rigidly mounted onto or dismounted from the nozzle of a .vacuum apparatus. For the'purpose of explaining the invention an example embodying the same has been shown in the accompanying drawing, in which. the same letters of reference have been used in all the views to indicate corresponding parts.

In said drawing Fig. l is a sectional elevation taken on the line'l-l of Fig. 3 and, showing the mouthpiece or nozzle of the apparatus,

Fig. 2 is a sectional elevation taken on the line 2--2 of Fig. 3 showing the downward movementof a flexible rockable member as hereinafter described, andl Fig. 3 is a top plan view of Fig. 1.

In the examples shown in the figures the mouthpiece of thevvacuum cleaning apparatus comprises a tubular member b having an extension a adapted to be secured to a tubular handle or flexible tube. On the topV 40 of the tubular member b an electromagnet c, d is mounted the armature e of which is fixed to a curved arm g rockingly mounted at f. The arm g is passed into the casing through a slot m and it carries a contact i which in theV out-of-serviceV position of `the parts is pressed by `a spring k into the engagement with a Contact lc, the said contacts z' and lc being included in the circuit of the coil d. The front end of the arm g is curved downwardly and through an opening m into the casing b, and it carries a beating membe cleaned, the exhauster is started and the 'electromagnet c, d is energized. Thereby -of the arm g, the member n has a rubbing 427,017, and inGermany February 19, 1929.

ber n adapted upon operation of the device to act-on the surface to be cleaned. The operative parts are covered by a hood o. Preferably, the beater n is removably fixed to the arm g so thatl at any time a beating 5 member suitable for the purpose aimed at may be fixed to the arm.

In the operation of the apparatus the mouthpiece b is passed across the surface to the armature e is oscillated upwardly and downwardly and by reason of the elasticity action on the surfaceto be cleaned in addition to the beating action.

I claim:

1. In a vacuum cleaner, a tubular mouthpiece adapted to be connected with a vacuum device, a rockable arm on the mouth' piece and having a free lashing end, beating means on the rockable arm mounted within the mouthpiece for acting on a surface to be cleaned, and a magnetic hammer break for operating said rockable arm, the free lashing end of said rockable arm having a curved portion extending through an opening and into the interior of said mouthplece.

2. In a vacuum cleaner, a tubular mouth` piece adapted to be connected with a. vaci uum device, a rockable arm on the mouthpiece and having at one end thereof a projecting substantially longitudinally arcuate beating and rubbing flexible portion for acting against a surface to be cleaned, whereby said arm by its rockin movement will cause said beating and rub ing portion to bind flexibly when acting against the resistance of the surface t0 be cleaned, to cause beating and rubbing movements against said surface, and means for operating said rockable arm.

3. In a vacuum cleaner, av tubular mouthpiece adapted to beconnected with a vac-y uum device, an arm rockingly mounted on the outside of said mouthplece and having a free end extending into the mouthpiece,

a, beating member secured to the :free end of said arm within said mouthpiece, and an electromagnet for operatin said arm.

4. In a vacuum cleaner, a tu ular mouthpiece adapted to be connected with a vacuum devlce, an arm rockingly mounted on said mouthpiece and having a curved Hexible end bent into said mouthpiece, a beating member fixed to the free end of said arm in position for engaging the surface to be cleaned and means for imparting' oscillating movement to said arm.

5. In a vacuum cleaner, a tubular mouthpiece adapted to be connected with a vacuum device, a rockable arm n'the mouthpiece, a exible extension in continuation of one end of the arm, positioned for acting on a surface to be cleaned and adapted, when the arm is rocked, to havean impinging and rubbing action on the surface to be cleaned, and means for operating said rocking arm.

6. In a vacuum cleaner, a tubular mouthpiece adapted to be connected with a vacuum cleaner a rockable arm on the exterior of the mouthpiece, a beating element within the mouth iece, an arcuate extension on one end of t e -arm extending through a guide opening into the interior of the mouthpiece and carrying the beater element therein, and means for operating said rockable arm.

In testimony whereof I hereunto ax my signature. v

CARL OTTO.
